The tumor in the lung is then called metastatic breast cancer, not lung cancer. Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M". In overall stage grouping, metastasis places a cancer in Stage IV. The possibilities of curative treatment are greatly reduced, or often entirely ...
Cancer, malignant neoplasm: Malignant tumor (right) spreads uncontrollably and invades the surrounding tissues; benign tumor (left) remains self-contained from neighbouring tissue: Specialty: Oncology: Symptoms: Fatigue, lump(s), change in skin, abnormal bleeding, prolonged cough, unexplained weight loss [1] Risk factors
Symptoms of cancer metastasis depend on the location of the tumor. When cancer begins, it produces no symptoms. Signs and symptoms appear as the mass grows or ulcerates. The findings that result depend on cancer's type and location. Few symptoms are specific. Many frequently occur in individuals who have other conditions.
Metastatic melanoma may cause nonspecific paraneoplastic symptoms, including loss of appetite, nausea, vomiting, and fatigue. Metastasis (spread) of early melanoma is possible, but relatively rare; less than a fifth of melanomas diagnosed early become metastatic. Brain metastases are particularly common in patients with metastatic melanoma. [17]
Metastatic carcinoma is cancer that is able to grow at sites distant from the primary site of origin; thus, dissemination to the skin may occur with any malignant neoplasm, and these infiltrates may result from direct invasion of the skin from underlying tumors, may extend by lymphatic or hematogenous spread, or may be introduced by therapeutic ...
For other types of cancer of unknown primary, a PET-CT offers uncertain benefit. [7] The pattern of spread may suggest the location of the primary site. For example, metastatic cancer found in the upper body is more likely to have an origin above the diaphragm, at sites such as the lung and breast. If the metastatic cancer appears first in the ...
